Every trip-cost site is a trick to send you somewhere. They round up so you under-feel sticker shock. They round down so you book. They quote ranges so wide you cannot plan a budget.
We do not book the trip. We have no incentive to round either way. So we don't.
We tell you what we think Tokyo for ten days costs you, mid-range, two travelers, economy. We say $3,840. We say ±8%. We show you the six lines, the assumptions behind each one, and the bands on the fare data the model ran against.
If we are wrong, we publish it. Every quarter. Median absolute error against actual reported spend from a thousand paid users who shared their receipts. The number is usually 9.4%. When it is worse than that, we say so.
If you want the round number — “Tokyo is $5,000-ish” — we are not the site for you. Plenty of options exist.
If you want the defensible number you can pitch to a partner, a client, a finance team, or a skeptical spouse — that's what we built.
TripBudget is built by a small team that has spent a decade in fintech, travel ops, and payment infrastructure. We started this because we got tired of clients asking us "how much will this cost?" and not having a confident answer. So we built one.
